Tragedy on San Francisco Bay: Coast Guard Suspends Search After Boat Capsizes Near Alcatraz, Leaving 1 Dead and 3 Missing

Folks, a tragedy unfolded in the waters of San Francisco Bay on Tuesday afternoon — one that turned a family memorial service into a desperate search-and-rescue operation that would span 23 hours and cover nearly a thousand square nautical miles. The Coast Guard has now suspended its search for three missing people after a boat capsized near one of America's most infamous landmarks.

Tragedy on San Francisco Bay: Coast Guard Suspends Search After Boat Capsizes Near Alcatraz, Leaving 1 Dead and 3 Missing

San Francisco, CA – July 15, 2026 — A family outing meant to scatter a loved one's ashes in San Francisco Bay turned deadly on Tuesday when a 49-foot cabin cruiser capsized roughly 600 yards off Alcatraz Island, leaving one person dead, three missing, and 16 survivors pulled from the frigid waters.

The Capsizing Near Alcatraz

At approximately 3:35 PM local time on July 14, the San Francisco Fire Department received reports of a vessel on fire roughly 600 yards from Alcatraz Island, between the former prison and the Golden Gate Bridge. When first responders arrived, they found no evidence of a fire. Instead, they discovered a three-deck pontoon boat named the Volare had already capsized and was mostly submerged, with only its upper deck visible above the waterline.

The vessel, registered out of Stockton, California, had departed from the St. Francis Yacht Club and was returning from Angel Island when it was overcome by conditions. The boat's engine was still running, and fuel was leaking into the bay as rescuers arrived.

Fire Chief Dean Crispen said the San Francisco Police Department's marine unit found the vessel with one person in the water while the remaining occupants were inside the top compartment before being pulled to safety. Witnesses initially mistook steam for smoke, leading to the fire report.

Who Was Aboard the Volare

Twenty people were on board the Volare at the time of the capsizing — an extended family group gathered for a memorial service to scatter a loved one's ashes over the bay. Authorities confirmed no children were aboard. All passengers were either related or close family friends.

Sixteen people were rescued from the water. Three were hospitalized in stable condition, and the boat's pilot was also hospitalized but has since been released. Three passengers remain unaccounted for, and their names have not been released by authorities.

The Loss of Clifford Joseph Boisa

Clifford Joseph Boisa, 79, of Sutter County, was recovered from the water and pronounced deceased despite life-saving measures at the scene. Boisa had served as a reserve deputy sheriff for Sutter County since 1987 — a community figure whose decades of volunteer service was cut short during what was meant to be a solemn family ceremony.

A dog that was on board also died in the incident, officials confirmed.

The Search Operation

The U.S. Coast Guard, San Francisco Fire Department, San Francisco Police Department marine unit, and Oakland Police Department all contributed to the search effort. Eleven rescue vessels, helicopters with thermal imaging, divers, tide predictions, and drift modeling were deployed across a search area covering approximately 950 nautical square miles.

Coast Guard Sector San Francisco Commander Capt. Jarod Tosczko said the search was suspended at sunset on Wednesday, July 15, after crews spent roughly 23 hours searching without success. "We have completely saturated the search area," Tosczko said at a Wednesday news conference, thanking the Good Samaritans who helped rescue people from the water.

Officials acknowledged it is possible the three missing passengers are trapped inside the Volare, which rests approximately 130 feet below the surface. Investigators plan to deploy an underwater drone to locate the vessel before determining whether to attempt recovery of the victims and raise the boat.

Dangerous Conditions on the Bay

The waters around Alcatraz Island are notoriously hazardous. Strong summer winds, rapidly changing tides, and shifting currents create conditions that can overwhelm even experienced boaters. Authorities say the Volare appears to have taken on a wave, become swamped with water, rolled over, and sank, though the investigation into the exact cause remains ongoing.

The water temperature at the time of the incident was approximately 60 degrees Fahrenheit — cold enough to cause cold shock and incapacitation within minutes for anyone without a life jacket. By the morning of July 15, the temperature had risen only slightly, to 64.8 degrees, according to U.S. Geological Survey monitoring data.

The boat sank in roughly 120 to 130 feet of water in an area notorious for suddenly hazardous conditions. San Francisco Fire Chief Dean Crispen noted the challenging conditions during a news briefing, saying the search would continue as long as possible.

Witness Accounts: Fishermen Describe Frantic Rescue

Commercial fishermen Mike Montoya and Justin Marceline were on the water nearby when the Volare went down and rushed to help. They described a chaotic scene as passengers fought to escape the sinking vessel.

"There was even people banging at the windows as they were like filing out, and as soon as people were hitting the water, we were just trying to pick them up as fast as we can," the fishermen told NBC Bay Area. "Some people didn't even have life vests on and they were drowning."

Their quick actions helped pull multiple survivors from the 60-degree water, but the accounts of passengers without life jackets highlighted a preventable element in a tragedy that continues to unfold. The Coast Guard later confirmed that life jackets were available on the Volare but not all passengers were wearing them when the wave struck.

Both fishermen remained on scene for roughly 40 minutes after their initial rescue efforts, assisting incoming Coast Guard vessels by marking the debris field with floating markers before returning to port. Their accounts have been submitted as part of the ongoing investigation into the capsizing.

What This Means

The suspension of the search after 23 hours and 950 square nautical miles of coverage marks a grim milestone in this incident. The Coast Guard's decision to end active searching signals that the three missing passengers are presumed lost, likely trapped inside the sunken vessel at a depth of 130 feet.

Coast Guard Captain Jarod Tosczko acknowledged the possibility during a Wednesday press conference, announcing that investigators plan to deploy an underwater drone to locate the Volare before deciding whether recovery operations are feasible. The technical challenges of raising a three-deck pontoon boat from 130 feet of cold, tidal San Francisco Bay water are significant and could take weeks to plan.

San Francisco Mayor Daniel Lurie expressed condolences to the victim's family and thanked the multiple agencies — Coast Guard, San Francisco Police, Oakland Police, and fire crews — for their coordinated response. "This is an all-hands-on-deck search and, hopefully, rescue," he said earlier in the operation.

Maritime experts point out that pontoon-style vessels, while popular for calm inland waters, face elevated risks in open-bay environments where waves and swells can overwhelm low freeboard designs. The incident reinforces the critical importance of life jackets, even on short ceremonial voyages, and highlights how rapidly San Francisco Bay can turn deadly. The absence of life jackets on at least some passengers — as confirmed by the fishermen who first arrived on scene — represents a missed opportunity for survival in 60-degree water.

The tragedy also raises questions about marine safety protocols for memorial services conducted on rented charter vessels. Unlike commercial passenger vessels that require strict adherence to Coast Guard safety regulations, private recreational charters operating with family groups fall under less rigorous oversight — a regulatory gap that safety advocates may push to close in the wake of this incident.

As families in Stockton and Sutter County mourn the loss of Clifford Joseph Boisa and wait for word on the three still missing, the Volare sits 130 feet below the surface — a steel-and-fiberglass tomb that may hold answers investigators are not yet ready to retrieve.
